DescriptionThe MAX9310A is a fast, low-skew 1:5 differential driver with selectable LVPECL inputs and LVDS outputs,designed for clock distribution applications. This device features an ultra-low propagation delay of 340ps with 48mA of supply current.
The MAX9310A operates from a 3V to 3.6V power sup-ply for use in 3.3V systems. A 2:1 input multiplexer is used to select one of two differential inputs. The input selection is controlled through the CLKSEL pin.
This device features a synchronous enable function.The MAX9310A LVPECL inputs can be driven by either a differential or single-ended signal. A VBBreference voltage output is provided for use with single-ended inputs. The device can also accept differential HSTL signals.
The MAX9310A is offered in a space-saving 20-pin TSSOP package and operates over the extended tem-perature range from -40°C to +85°C.
